After configuration, the setpoints can be saved in a file which could then be flashed into other AX1307x0 controllers over the CAN network.

  • Page 6: Overview Of Controller

    1. OVERVIEW OF CONTROLLER 1.1. Description of CAN to 2 Analog/Digital Signals and 1 Relay Output Converter This User Manual describes the architecture and functionality of the CAN to 1 Relay and 2 Analog Outputs Converter (CAN-1RLY-2AOUT). It accepts power supply voltages from 9 to 36 VDC. All logical function blocks on the unit are inherently independent from one another but can be configured to interact with each other.

  • Page 7: Relay Output Function Block

    1.2. Relay Output Function Block The following sub-sections will explain in more detail the functionalities and available setpoints/parameters. 1.2.1. Relay Output Functionality The relay output has 2 states: Normally Open and Normally Closed. It has 3 pins associated with it: Normally Closed (NC), Normally Open (NO), and Common (C).

    In case the “Relay Enable Response” is ‘Enable When ON Else Keep State’, the relay output will be commanded according to the signal of the “Relay Control Source” and “Relay Control Number” only when the signal of the “Relay Enable Source” and “Relay Enable Number” is ON.

  • Page 10: Analog Output Function Block

    1.3. Analog Output Function Block The controller has 2 analog/digital outputs can be configured and they are inherently independent of each other. The Analog Output Type parameter determines what kind of signal the output produces. Changing this parameter will update other parameters in the group to match the selected type.
  • Page 11 1.3.1 Analog Current/Analog Voltage Current Outputs can be configured to different ranges as 0-20mA, 4-20mA and 0-24mA and Voltage Outputs can be configured to be bipolar or unipolar, 0-5V, 0-10V, -10V to 10V and -5V to 5V. To drive the output to different ranges, simply setting the “Output at Minimum Command” and “Output at Maximum Command”...
  • Page 12 In a ‘Normal Logic’ response, when the Control input commands the output ON, then the output will be turned ON. However, in an ‘Inverse Logic’ response, the output will be ON unless the input commands the output ON, in which case it turns OFF. If a ‘Latched Logic’...

  • Page 13: Lookup Table Function Block

    1.4. Lookup Table Function Block Figure 3 – Lookup Table Function Block Lookup Tables are used to give an output response of up to 10 slopes per input. The array size of the Response [ ], Point X [ ] and Point Y [ ] setpoints shown in the block diagram above is therefore 11.

  • Page 14: X-Axis, Input Data Response

    1.4.1. X-Axis, Input Data Response In the case where the X-Axis Type” = ‘Data Response’, the points on the X-Axis represents the data of the control source. For example, if the control source is a CAN Receive message, setup as a 0-5V type, with an operating range of 0.5V to 4.5V, the X-Axis will be setup to have a default “Point 1 –...

  • Page 15: Default Configuration, Data Response

    1.4.3. Default Configuration, Data Response By default, all Lookup Tables in the ECU are disabled (“X-Axis Source” equals ‘Control Source Not Used’.) If they were to use the default settings for Inputs 1 and 2 instead as the X-Axis and output current (in mA) they could be used to control the Analog Output 1.

  • Page 16: Point To Point Response

    For example, with a 0.5 to 4.5V input (X-Axis) driving a 0 to 1500mA output (Y-Axis), the default points would be setup as per figure (a) below. However, a 100Ω to 54kΩ input (X-Axis) representing 120ºC to -30ºC (Y-Axis) would be setup as per figure (b) below. In each case, the user would have to adjust the table for the desired response.
  • Page 17 Figure 5 – Lookup Table “Jump To” Data Response Lastly, any point except (0,0) can be selected for an ‘Ignore’ response. If “Point N – Response” is set to ignore, then all points from (X ) to (X ) will also be ignored. For all data greater than , the output from the Lookup Table function block will be Y N-1.

  • Page 18: X-Axis, Time Response

    1.4.5. X-Axis, Time Response As mentioned in Section 1.4, a Lookup Table can also be used to get a custom output response where the “X-Axis Type” is a ‘Time Response.’ When this is selected, the X-Axis now represents time, in units of milliseconds, while the Y-Axis still represents the output of the function block. In this case, the “X-Axis Source”...
  • Page 19 In a time response, the interval time between each point on the X-axis can be set anywhere from 1ms to 24 hours. [86,400,000 ms] One final note about the Lookup Tables is that if a digital input is selected as the control source for the X-Axis, only a 0 (Off) or 1 (On) will be measured.

  • Page 21 This function block is obviously the most complicated of them all, but very powerful. The Programmable Logic can be linked to up to three tables, any one of which would be selected only under given conditions. Any three tables (of the available 10) can be associated with the logic, and which ones are used is fully configurable.

  • Page 23: Conditions Evaluation

    1.5.1. Conditions Evaluation The first step in determining which table will be selected as the active table is to first evaluate the conditions associated with a given table. Each table has associated with it up to three conditions that can be evaluated. Argument Z is always a logical output from another function block.
  • Page 24 1.5.2. Table Selection In order to determine if a particular table will be selected, logical operations are performed on the results of the conditions as determined by the logic in Section 1.5.1. There are several logical combinations that can be selected, as listed in Table 11. Default Table Cnd1 And Cnd2 And Cnd3 Cnd1 Or Cnd2 Or Cnd3...

  • Page 25: Logic Block Output

    1.5.3. Logic Block Output Recall that Table X, where X = 1 to 3 in the Programmable Logic function block does NOT mean Lookup Table 1 to 3. Each table has a setpoint “Table X – Lookup Table Block Number” which allows the user to select which Lookup Tables they want associated with a particular Programmable Logic Block.

    1.6. Math Function Block Figure 11– Math Function Block There are four mathematic function blocks that allow the user to define basic algorithms. A math function block can take up to four input signals, as listed in Table 2 in Section 1.2.2. Each input is then scaled according the associated limit and scaling setpoints.

  • Page 29 As mentioned earlier, a CAN Receive function block can be selected as the source of the control input for the output function blocks. When this is the case, the “Received Data Min (Off Threshold)” and “Received Data Max (On Threshold)” setpoints become the minimum and maximum values of the X-axis used in the linear calculations.

  • Page 30: Can Transmit Function Block

    1.8. CAN Transmit Function Block Figure 13– CAN Transmit Function Block The CAN Transmit function block is used to send any output from another function block (i.e.relay, status or analog signals) to the J1939 network. Normally, to disable a transmit message, the “Transmit Repetition Rate” is set to zero. However, should message share its Parameter Group Number (PGN) with another message, this is not necessarily true.

  • Page 31: Conditional Block

    This Controller supports up to 5 unique CAN Transmit Messages, each CAN transmit message has four associated signals, all of which can be programmed to send any available data to the CAN network. “Signal X Data Source” setpoint together with “Signal X Data Number” setpoint define the signal source of the message.
  • Page 32 Figure 14: Conditional Block Diagram Each Conditional Block offers two conditions. Both compare two inputs, which can hold a logical value or an integer value. The output of the conditions can only be true or false and will be compared by Operator 3 with a logical operator. This comparison is the result of the Conditional Block and can control any output source.
